Social media has transformed the web into a hyper-connected social space that is inundated by a flood
of social signals that reflects the activities of the members, and contributes to the dynamic of the
interaction. In this context, the participants decode, process and emit information for making sense of
this social world, and for acting upon it. The objective of this paper is to explore the implication of this
setting for an application in the context of supporting creativity online. More specifically, we examine
the effect of the massive circulation of this social information and its management on systems
supporting the collective creative process online.

Due to advances of technology including faster and ubiquitously accessible
Internet connection, on-line gaming have grown tremendously in the
last couple of years. The aim of this paper is to investigate whether escapist motives
for playing games are linked to strengthening of weak ties through on-line
gaming. The research investigates Facebook and other on-line games separately.
A surprising result is that while most of the investigated escapist motives are
positively correlated with strengthening of weak ties, the mundane breaking
motive is negatively correlated with strengthening of weak ties.

Social Media is a new phenomenon that impacts businesses, society and individuals. Social media has swept into the business world, disrupting businesses, bringing new opportunities and challenges. The use of social media in organizations has the potential to shape the “future of the work”. Both consultancy reports and scholarly articles highlight and discuss the new opportunities and organizational benefits provided by social media to change the current top-down (i.e. initiated by management) business model to a more collaborative and bottom-up (i.e. initiated by employees) approach. Such a model is customizable to specific user needs, empowering employees to design specific workflows thus helping them to work more effectively. Using social media, personal knowledge can be synergized into collective knowledge through social collaborative processes that may facilitate externalization of knowledge, fostering creativity and innovation. All these processes have the potential to lead to knowledge creation through interaction and collaborative processes and thereby increase companies’ competitiveness. However the successful deployment of social media for internal communication and facilitation of knowledge sharing and collaboration in organizations is difficult. Based on quantitative as well as qualitative data from 13 Danish organizations, we investigate the following research question: What is the business value of social media in organizations as perceived by the employees? Based on the data analysis, the paper derives a model of factors associated with the perceived business value of social media.

This paper aims to elaborate on the role of user
modelling for personalization and enhanced attention support.
User modelling is an important element in the management of
personal profiles and identity of users, but also a key element
for providing adaptive features and personalized interaction.
In this paper, we present personalization as the process
consisting on the customization, and the adaptation of the
interaction along the structure, the content, the modality, the
presentation and the level of attention required. The paper
surveys personalization techniques and provides concrete
examples of personalized interaction. In particular, the paper
focuses on the role of user modeling for enhanced, personalized
user support within interactive applications. The key
contribution of the paper is to propose a framework of
personalization techniques and to identify new forms of
personalization that aim at taking into account human
cognitive capabilities and emotions.
